Consumer fingertip pulse oximeters like the Pc-60fw generally provide readings that can vary in accuracy depending on conditions. Factors like cold hands, nail polish, movement, or poor circulation can affect readings. Most devices in this category work best when used on clean, warm fingers in a stationary position.
The digital display typically shows SpO2 percentage and pulse rate, though the exact display features of this specific model aren't clearly documented. Users should be aware that readings from consumer devices may differ from those obtained with professional medical equipment and should not replace proper medical assessment when health concerns arise.
